Patent number: 7014885Abstract: A device and method for depositing a material of interest onto a receiving substrate includes a first laser and a second laser, a receiving substrate, and a target substrate. The target substrate comprises a laser transparent support having a back surface and a front surface. The front surface has a coating that comprises the source material, which is a material that can be transformed into the material of interest. The first laser can be positioned in relation to the target substrate so that a laser beam is directed through the back surface of the target substrate and through the laser-transparent support to strike the coating at a defined location with sufficient energy to remove and lift the source material from the surface of the support. The receiving substrate can be positioned in a spaced relation to the target substrate so that the source material is deposited at a defined location on the receiving substrate.Type: GrantFiled: July 19, 2000Date of Patent: March 21, 2006Assignee: The United States of America as represented by the Secretary of the NavyInventors: Alberto Piqué, Raymond Auyeung, James Fitzgerald, Douglas B.

Publication number: 20030157253Abstract: A multicomponent film on a substrate can be annealed at higher temperatures in oxygen by using a specifically designed annealing vessel. The vessel is formed of a multicomponent material which has at least all of the components of the first multicomponent material of the film or, in the case where there are nonvolatile components, then the vessel is formed of a second multicomponent material which has at least the same composition of relatively volatile components as the first multicomponent film. As the multicomponent film is annealed for a sufficient time within the vessel the multicomponent film remains in contact with a vapor of the first multicomponent material and the vessel material. This process called bomb annealing prevents loss of volatile components from the film and roughening of the film surface and leads to films with lower dielectric loss. Preferred thin film materials are ferroelectric materials although any material could be used.Type: ApplicationFiled: August 15, 2002Publication date: August 21, 2003Inventors: James Horwitz, Douglas B. Chrisey, Adrian Carter, Manfred Kahn
